Requirements: When more than one button is clicked, users will then be able to click on "proceed-button".
Current situation: I am making a cinema web page. Users will get to choose their preferred seats. When the seat is chosen, they will then be able to click on "proceed-button" to pay. However, i have difficulty implementing this function. I know that i needed to use the visibility-hidden function.
The following is my code:
var buttons = document.getElementsByClassName("button");
var count = 0;
var disp = document.getElementById("display");
for (let i = 0, l = buttons.length; i < l; i++) {
buttons[i].addEventListener('click', function() {
buttons[i].classList.toggle('active');
if (this.classList.contains("active")) {
count++;
if (this.classList.contains("active") > 1) {
function proceedButton() {
document.getElementById("pButton").style.display = "visible";
}
} else {
document.getElementById("pButton").style.display = "block";
}
} else {
count--;
}
disp.innerHTML = count;
})
}
function proceedButton() {
var x = document.getElementById("payment-section");
if (x.style.display === "none") {
x.style.display = "block";
}
}.button {
background-color: #423F3E;
height: 30px;
width: 30px;
margin: 5px;
border-radius: 10px;
border: none;
float: left;
}
.button.active {
background-color: #F7EA00 !important;
}<div class="seats-layout">
<div class="row">
<input type="button" id="button1" class="button" />
<input type="button" id="button2" class="button" />
<input type="button" id="button3" class="button" />
</div>
<div class="row">
<input type="button" id="button1" class="button" />
<input type="button" id="button2" class="button" />
<input type="button" id="button3" class="button" />
</div>
</div>
<p> Button Clicked <span id="display">0</span> Times</p>
<input type="submit" value="Proceed" onclick="proceedButton()" id="pButton" class="proceed-button" />
```
<div id="payment-section" style="display: none">
<h1>Payment</h1>
</div>
```use document.querySelectorAll to returns all elements in the document that matches a specified CSS selector(s), as a static NodeList object.
function proceedButton() {
var x = document.getElementById("payment-section");
var item_click = document.querySelectorAll('.active').length;
if (item_click>1) {
x.style.display = "block";
}else{
x.style.display = "none";
}
}
